JIT Debugging failed with the following error: Access is denied.

A friend working on ASP.NET got the following error message recently and sent my this error whether I got on idea about this .NET Framework exception.
Actually the error is self explaining. The user or the account 'machinename\ASPNET' has unsufficient priviledges.
A quick resolve for this problem is adding the related user to the Debugger Users group.
